Provided are a washing machine and a method for controlling the same. The method for controlling a washing machine includes supplying water to a tub, driving a driving unit to perform tumbling to rotate a drum disposed in the tub, calculating a water level variation in the tub, and displaying freeze state information on a display unit when the calculated water level variation is less than a reference water level variation.

A laundry treating apparatus including a drum holding a washing object, a drive unit rotating the drum, a drive controller, a display unit with an input unit accepting drive unit control orders, and a display communicating treating progress of the washing object. The display unit having a controller with an input data processing unit, an output data processing unit, and a processing unit control program for running the input and output data processing units. The laundry treating apparatus further including a system managing unit enabling the drive controller and display unit to exchange data with the display unit controller, ordering operation of the display unit, and running the processing unit control program, a list storage unit storing a program list the display unit controller runs, and a monitoring unit for initializing the system managing unit if the processing unit control program is not at the list storage unit.

A user interface apparatus includes a first display unit that is configured to display a plurality of first items, a wheel input unit that is positioned proximate a first side of the first display unit, a button input unit that is positioned within a circumference of the wheel input unit, and a second display unit that is positioned within the circumference of the wheel input unit. The wheel input unit is rotatable and is configured to, based upon being rotated, output a scroll command to scroll the plurality of first items. The button input unit is configured to, based upon being pressed, output a selection command to select a first item from the plurality of first items. The second display unit is configured to display the selected first item.

A laundry treatment apparatus includes a cabinet having an upper surface, the upper surface being configured to receive an object thereon, a drawer adapted to be drawn from the cabinet, a drum disposed in the drawer and defining a space for receiving laundry, a driving unit configured to rotate the drum, a control unit configured to control the driving unit, and a connector unit configured to impact an ability of the control unit to control operation of the driving unit based on whether or not the object is placed on the upper surface of the cabinet by preventing the control unit from controlling operation of the driving unit based on the object being absent from the upper surface of the cabinet and by allowing the control unit to control operation of the driving unit based on the object being placed on the upper surface of the cabinet.

A washing machine includes a machine housing, a tub that is suspended on a plurality of support arms in the machine housing, and a washing drum that is rotatably mounted in the tub, at least one of the support arms being equipped with a force sensor, which generates a force measurement signal that is representative of the force acting upon the respective support arm. Moreover, the washing machine is equipped with a level sensor, which generates a level signal that is representative of the water level in the washing drum, and an electronic control unit that processes the force measurement signal and the level signal, and which is configured to control the sequence of a washing program of the washing machine in dependence on the force measurement signal and the level signal.

Washing machine appliances and methods for determining load masses are provided. A method includes accelerating rotation of a basket of the washing machine appliance from a first speed to a second speed greater than the first speed and for a predetermined time measured for acceleration of the basket from the first speed; measuring, during the accelerating step, a check speed of the basket at the predetermined time; and measuring, during the accelerating step, an acceleration time for the tub to accelerate from the first speed to the second speed. The method further includes discontinuing acceleration of the basket after the second speed and the predetermined time have reached; and measuring a coast time for coasting of the basket from the check speed to the first speed. The method further includes determining a load mass in the basket based on the check speed, the acceleration time, and the coast time.

The invention relates to a washing/drying machine equipped with a filter cleaning device for removing filaments released by laundry items during the washing/drying cycle. For this purpose, the cleaning device comprises nozzles arranged in a spider-like pattern, which spray water onto the filtering wall, on the side thereof facing towards the drying tub.

Provided are a mist generator and a washing machine. The mist generator can provide mist having small enough particles. The mist generator includes: a housing having a discharge part; a mist generation unit having a mist spraying nozzle for spraying a mist and causing the mist sprayed from the mist spraying nozzle to collide in the housing to generate a mist with particles smaller than those of the sprayed mist; and a discharging unit for generating an airflow toward the discharging opening in the housing, so that in case of nonuse of a blowing fan, the mist with smaller particles generated by the mist generation unit is discharged from the discharging opening along with the airflow.

System and method for dispensing product to a washing machine. A chemical dispensing system includes a system controller, machine interface, and pump controller that communicate through serial data buses. The system controller provides a user interface, retrieves washing machine status information from the machine interface, and issues product dispensing commands to the pump controller. The pump controller monitors pump status and dispenses product in response to commands from the system controller. The pump controller: (1) determines pump activation periods based on calibration data stored in a pump controller memory; (2) tracks pump usage and adjusts the activation period to compensate for pump wear as the pump ages; (3) disables the pump if conditions exists that preclude operating the pump; (4) monitors product levels, and (5) reports pump status to the system controller. Integral channels are included in the pump housing to provide stress relief to a squeeze tube.

A washing machine having a breathing lamp set and a method for controlling the same are provided. The breathing lamp set is disposed on an outer wall or inner wall of a housing of the washing machine and is composed of a plurality of breathing lamps. The washing machine further includes a controller, configured to change, according to work process changes of the washing machine, a quantity ratio of lighted breathing lamps to dimmed breathing lamps among the plurality of breathing lamps in the breathing lamp set. The method for controlling the washing machine having the breathing lamp set includes step S1: changing, by the controller, the quantity ratio of lighted breathing lamps to dimmed breathing lamps among the plurality of breathing lamps in the breathing lamp set, so as to discriminately display different work states of the washing machine.
